I analyzed PG's profiles extensively to determine average velocity increases for LHP's between their sophomore and junior years. Item #4 is based on height increase. Although the data is limited to LHP's, one can reasonably assume a similar increase in velocity for RHP's.
1) Average Velocities for All LHP's at All PG Regular (Non-State) Showcases in 2006:
Sophomore: 78.18
Junior: 81.97
Increase: 3.79
2) Average Velocities for All LHP's at All PG State Showcases in 2004, 2005, and 2006:
Sophomore: 77.97
Junior: 79.43
Increase: 1.46
3) Average Velocities for LHP's Who Appear in the 2005 Top 1000 Player List:
Sophomore: 82.54
Junior: 86.11
Increase: 3.57
1-100 Average Increase : 5.71
101-500 Average Increase: 3.94
501-1000 Average Increase: 2.09
4) Average Velocity Increase Between Sophomore and Junior Year for All LHP's in 2005 National Showcase, Based Upon Player Height Increase:
Player Did Not Grow: 2.24
Player Grew One or More Inches: 3.73
Notes and Conclusion
*Players who did not have multiple showcases in which to determine improvement are not included in the data.
*Analyzing the data in PG's Top 1000 Player List for 2005, it shows that the top 100 players experienced a greater velocity increase than the bottom 500 players.
